Jon,

Yeah, I had heard that argument as well. Unfortunately, I've tried converting and using the Pronto codes from the listings here, and have had no luck.

Of course, I started with Pronto codes for the power, and those converted codes didn't work either. With a bit of work I was able to figure out that the converted verions were missing a hex digit and had screwed up part of the lead-in as well. By comparing with the codes I had downloaded from my remote, I could figure out what corrections to make and that gave me the working codes I posted above.

I have not had success trying the same on the input codes, but haven't given up yet. Thanks for your help.
